I remember the first time Kumon was suggested to me.
Daily practice. Short sessions. Guaranteed results.
It sounded reassuring. Structured. Safe.
As a parent, that kind of promise is hard to ignore.
As an educator, I wanted to understand what actually sits behind it.
Tori Kumon
Toru Kumon (1914–1995) was a Japanese mathematician and educator. He was born in Japan, in Kochi Prefecture. Kumon graduated from Osaka University with a degree in mathematics and worked for many years as a private tutor, preparing students for university entrance exams.
In 1954, Kumon’s son came home from school. His mother found a crumpled piece of paper in his pocket. It was a mathematics test. And the results were, sadly, disappointing.
It felt painful and unfair. A mathematician’s son, and yet he was failing math.
Kumon began teaching his eldest son himself and soon realised that the problem did not start in that particular year. The gaps went back to the early grades. It was these missed foundations, Kumon concluded, that were causing his son’s difficulties.
Every evening, Toru Kumon prepared a single page of math problems for his son. Solving them took about thirty minutes. The tasks matched the child’s actual abilities. When addition became fluent, Kumon made the material slightly more difficult. Only slightly. Always just within reach.
This is how his approach to teaching one of the most challenging school subjects was born.
This is how Kumon began.
What the Method Is About
The core of the Kumon method is very simple. Children regularly solve examples in addition, subtraction, multiplication, and division. They practise until these operations become automatic, almost effortless.
Only once a strong foundation is built does the child move on.
For Kumon, mastery meant being able to complete examples within a set amount of time. Two elements were essential.
Speed and accuracy.
In 1956, other parents became interested in the method. Kumon opened his first center in Osaka. In 1958, he founded an educational institute, developed unified standards, and the Kumon expansion began. Today, Kumon centers operate in 44 countries around the world.
Every Child Can Do This
Through the experience of thousands of students, Kumon became convinced that with the right approach, all children can cope with the school curriculum. More than that, almost every child has hidden potential, and this potential needs to be revealed.
The foundation of the Kumon method is self‑learning. Children work independently at home. Adults are needed mainly to check completed work.
Assessment and Enrolment
Enrolment is an opportunity to become familiar with the Kumon method, to understand how it works, and to ask questions. Most children undergo diagnostic assessment before starting.
The purpose of diagnostics is simple. To determine the child’s starting level.
Why does this matter?
So that a child can complete tasks with near‑perfect success and experience ease rather than struggle.
The goal is to reinforce a positive message.
“Math is easy. I can do this.”
Ideally, both parents or primary caregivers attend the assessment. After enrolment, children usually attend the center twice a week. On non‑attendance days, they complete short homework sessions lasting 10 to 20 minutes.
Inside the Classroom
In Kumon centers, children typically submit homework, receive new worksheets, and then complete classroom tasks. While waiting for results, they engage in math games.
For successful work, children receive stickers and Kumon dollars from the instructor. Then they go home.
Homework
Kumon is a year‑round program. This means seven days a week, 365 days a year. Yes, including holidays and weekends.
By choosing this path, parents and children commit to consistency and effort. The good news is that homework usually takes no more than 10 to 20 minutes per day.
Parents check work using answer books. The instructor selects homework carefully so the child progresses without developing resistance or aversion.
Motivation
At first glance, Kumon can feel boring and repetitive. Its essence lies in daily practice and gradual complexity.
Children complete only what they are capable of doing, step by step. Because of this, stress and emotional overload are usually avoided.
Stickers, Kumon dollars, and other small rewards are an integral part of the method. Studying every day becomes a habit.
Supporters claim that joy in learning does not disappear.
This is a debatable claim.
A small informal study I conducted online, across forums and YouTube, revealed many negative reactions. Statements like “I hate Kumon” and “Kumon steals precious minutes of my life” appeared surprisingly often.
The Program Structure
The program begins with many examples of basic arithmetic. Once this stage is completed, children move on to more complex operations. Multi‑digit division, fractions, equations, and beyond.
Progression is individual. Children move according to their abilities and mastery, not according to a fixed school schedule dictating when fractions or probability must be learned. This flexibility is one of the distinctive features of Kumon.
The Kumon math program contains 23 levels, from basic counting to calculus. There are 460 steps in total. Each step includes 10 worksheets. Altogether, this means completing approximately 4,600 worksheets.
Kumon believed that if a child does not want to learn, it is not the child’s fault. Teaching materials are often boring, and explanations unclear. Repetition, in Kumon’s view, is essential. Regular arithmetic practice builds the fluency required for mathematical confidence.
Kumon workbooks are sold worldwide. You can try them at home. Perhaps your child will enjoy solving problems. If so, you can consider enrolling in a nearby center or choosing distance learning.
Although, as an educator, I do not support this approach for preschool children.
